Quarkus embedded Derby database connection not possible

Question

We have a Quarkus application which needs to connect to an embedded derby database in order to store the application's data. The Derby DB driver in Quarkus is not able to use the provided URL to connect to the database jdbc:derby:memory:myDB and we get, at application start, the error message shown below. We encounter the same behaviour for a Derby DB persisted on files.

Our test application is a simple plain Quarkus application with the persistence configured to be an embedded Derby database (see Quarkus project setup below). We would appreciate any hint about what should be changed in the project setup, Quarkus configuration or application's code to have the Quarkus application properly connect to the Derby database.

application.properties

quarkus.datasource.db-kind=derby
quarkus.datasource.jdbc.url=jdbc:derby:memory:myDB

build.gradle (dependencies)

dependencies {
    implementation enforcedPlatform("${quarkusPlatformGroupId}:${quarkusPlatformArtifactId}:${quarkusPlatformVersion}")

    implementation 'io.quarkus:quarkus-hibernate-orm'
    implementation 'io.quarkus:quarkus-jdbc-derby'

    testImplementation 'io.quarkus:quarkus-junit5'
    testImplementation 'io.rest-assured:rest-assured'
}

Here the code of the test application

        Gift gift = new Gift();
        gift.setName(giftDescription);
        mEntityManager.persist(gift);
    }

}
